Decarboxylation is the process that activates compounds in cannabis such as THC. All cannabinoids contained within the trichomes of raw cannabis flowers have an extra carboxyl ring or group (COOH) attached to their chain. For example, tetrahydrocannabinolic acid (THCA) is synthesized within the trichome heads of freshly harvested cannabis flowers.
THCA has a number of known benefits when consumed, including having anti-inflammatory and neuroprotective qualities. But THCA is not intoxicating, and must be converted into THC through decarboxylation before any effects can be felt. The same goes for other cannabinoids present in cannabis.
